Everyone knows that Square-Enix isn't sure about which direction it should take it's FF franhcise. I beleive that some of SE's more solid titles are it's older FF titles. If fans would show that they would like to see more of their favorite titles (by downloading or purchasing), I don't think that SE would have much of a problem doing a remake, or compilation series of some, if not all of it's older titles.

With the release of Final Fantasy XIII, what's next? Not downloadable content, says the game's producer, Yoshinori Kitase.

"For Final Fantasy XIII, specifically, we're not considering any downloadable content," Kitase told Kotaku, ruling out even minor additions like downloadable costumes for the Final Fantasy XIII cast. "We feel that we've created a complete package with Final Fantasy XIII, so 100% of the game is present in the packaged product."

*As you may know, Final Fantasy gets it's name from being the "final"(finished) product.

"But that's not to say that for future Final Fantasy games we won't consider downloadable content," Kitase added. "The development teams are very interested in looking into what can be done for future titles. We're definitely open to considering that."

While he didn't mention it by name, Kitase may be referring to the next games in the Fabula Nova Crystallis trilogy, the more action oriented Final Fantasy Versus XIII and handheld entry Final Fantasy Agito XIII. The former is still currently announced as a PlayStation 3 exclusive, as Final Fantasy XIII once was. The latter is bound for the PSP, formerly planned for release only on mobile phones. Square Enix continues to evaluate the video game market for those titles, but wouldn't share "any exciting new announcements" with us about its plans.

Unlike Square Enix's other bestselling RPG series, Dragon Quest, which made the leap from PlayStation 2 to Nintendo DS and Wii, Kitase sees the main Final Fantasy series sticking to higher-definition consoles.

"In terms of Final Fantasy in general, the teams are really aiming for movie quality graphics and really dramatic storylines," he said. "For now, at least, consoles like the Xbox 360 and PS3 are the best place for this kind of cinematic experience to take place. We don't feel that it needs to transition necessarily to a handheld platform."

I don't think that it is a bad idea to keep main titles exclusive to Home Gaming Consoles.
I would be lying if I said that my Final Fantasy obsession has nothing to do with cutting edge graphics. That's what made Aeris' death scene come to life for me.
